It is important to diagnose developmental dislocation of the hip (DDH) by X-ray images. The aim of this study was to construct a diagnostic support system for DDH based on clinical findings obtained from the X-ray images of 154 female infants with confirmed diagnoses made by orthopedists. The Min-Max method of nonlinear analysis was applied to construct the diagnostic support system based on the measurement of four items in X-ray images : the outward displacement rate, upward displacement rate, OE angle, and a angle. This system was then applied to the data, we obtained good results that matched the confirmed diagnoses of orthopedists with an accuracy of 85.9%.
